I have a first-class honours degree from the University of Leeds. I’ve studied a wide range of subjects, including quantum physics, astrophysics and cosmology, medical physics, condensed matter physics, photonics and optics, mathematical logic, statistical mechanics and bionanophysics.

FFEA is a continuum mechanics biophysics simulation package designed for large, complex systems of biomolecules. It had been in use at Leeds for a few years (mostly for simulations of the motor protein Dynein), but now it’s free software that anyone can download. In this article I’ll talk about my work on the software so far and on the FFEA software publication in PLOS CompBio.

That is the question. A look at using bleeding-edge simulation techniques to understand the inhibition behaviour of Myosin-VII. I gave this presentation as part of my undergraduate final project in early 2016. It’s aimed at people who are familiar with basic physics concepts, but not biology or biophysics. You can find more technical information about the project here.

Myosin-VII is part of the Myosin family of motor proteins. It has a key role in the operation of biological structures in the eye and inner ear. Unfortunately, the dynamics of Myosin-VII and its inhibition are poorly-understood. This article details my use of FFEA (Fluctuating Finite Element Analysis), a coarse-grained continuum simulation package, to model the motion of Myosin-VII, and understand its inhibition behaviour.

As you probably know, halogen light bulbs are incandescent: they produce light as a side effect of being heated up. Conversely, LEDs are semiconductor devices, and prolonged heat can be very damaging to them. LED devices tend to be cooled in a similar way to computer CPUs – using a thermal interface (like thermal paste) a heatsink, and sometimes a fan as well. However, the effectiveness of these cooling methods can vary wildly, depending on the operational limits of the LED and the type of thermal interface being used. In this article, I’ll discuss the experimental methods I designed to characterise the thermal performance of LEDs using a variety of cooling methods.

The Bohr Magneton is a physical constant which is used to express the dipole moment of electrons. It corresponds to the angular momentum of an electron in the lowest orbital. The Bohr Magneton relates the splitting of atomic energy levels to the strength of an applied magnetic field. The Zeeman effect offers us an easy way to observe this splitting. In this lab report, I discuss a how to observe the Zeeman effect, and how it can be used to compute an accurate value for the Bohr Magneton.

A random walk (sometimes called ‘the drunkard’s walk’ describes the motion of a particle that undergoes a series of random steps. But what happens if that particle is a quantum particle? This article presents a few interesting ways of visualising this motion, using Python and matplotlib.

X-ray diffraction is an experimental technique that can be used to look at structures made of repeating lattices – anything from crystalline solids to crystallized biological molecules. In this lab report, I describe an experiment to determine the lattice parameters and Bravais lattice using 1-D X-ray diffraction patterns.
